New Canon introduced

J.K. Rowling provides a quick sketch of the Weasley family tree, including all the marriages and grandchildren not mentioned in the Epilogue of Deathly Hallows. She also includes Luna Lovegood's marriage to Rolf Scamander, and both James and Lily get middle names - Sirius and Luna respectively. It also introduces Percy Weasley's marriage to Audrey. She later placed this tree in the Room of Requirement section of her official website, where it was updated to include Draco Malfoy's marriage to Astoria Greengrass, and gives their son, Scorpius a middle name - Hyperion.
